1988 Chrysler Lebaron Convertible ... a lot of doubts

Few time ago, I bought a 1988 Chrysler Lebaron Convertible 2.5 Turbo. The car is in quite good conditions but it needs some works.

Unfortunatelly, the Operations Manual neither other information were in the car when I bought it, and this was not sold in Spain so It is really difficult to find any information for me and I have a lot of doubts ...
